UNITED STATES PATENT OFFICE.

PETER HINKEL, OF CHICAGO, ILLINOIS.

PAPER.

No Drawing.

To all whom it may concern:

Be it known that I, PETER HINKEL, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper,

the use of a single cylinder or Fourdriiner machine, or of course more than one cylinder may be used if preferred.

a 1n carrying out my invention I use a pulp of paper stock of any kind which may contain straw, wood pulp or any or all of the materials heretofore employed in the making of the paper with which I thoroughly inter-mix suflicient of the list or short cotton fiber such as is removable from cotton seed hulls. associated with the seed hulls is always impregnated with the cotton seed oil by the removal from the hulls to a sufficient extent to considerably improve the pliability of the paper, and, probably because of the presence of oil, enables the water to be Specification of Letters Patent.

This list or cotton fiber being closely Patented Nov. 23,1909.

squeezed from the paper more readily by the rolls than has heretofore been possible. I find in practice that but a single cylinder is required for rolling very thick board or felt, the product being very uniform and of greater resilienc and fiexlbility than when made as heretofore. Ordinarily about ten per cent. of-this so called cotton fiber is used though of course the amount will vary with the character of the paper stock used'and the finish it is-desired to impart to the paper.

Of course, if desired other fibers than that stated may be used and these may be treated with oil for the purpose of improving the paper and also facilitating the removalof the water therefrom.

I claim as m invention:

1. A paper oard or felt aper containing cotton fiber and as much 011 as the cotton fiber can absorb.

2. A paper board or felt containing a percentage of oily cotton fiber such as removed from cotton seed hulls and other fiber treated with oil. a

3. A composition of matter for the manufacture of paper comprising paper pulp mixed with fibers, oil added to the fibers, said fibers added after the neutralization of all alkalies.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
